Patient: Good day! My name’s Anna. The point is that, i have 1 day without a food per a week. (I have one fasting day weekly). This is my health live style. I plan to begin to use a contraceptive Nova Ring. Can i use a Nova Ring, if i have a one fasting day weekly? Whether the contraceptive effect will be kept? Please, reply!!!!!!!! P.S. English is not my native language. Sorry for mistakes.
